Advancements in Geothermal Energy: New Zealand's Ngā Tamariki Expansion Leads the Way By:  Robert Buluma Image:  Mercury NZ Delivers Fifth-Generation Unit at Ngā Tamariki – Strengthening Clean Energy Supply Geothermal energy, harnessed from the Earth's internal heat, represents one of the most reliable and sustainable sources of renewable power available today. Unlike solar or wind, which depend on weather conditions, geothermal provides consistent baseload electricity, making it a cornerstone for energy security in regions with suitable geological features. As the world grapples with climate change and the need to transition from fossil fuels, geothermal is gaining renewed attention. In 2026, global investments in geothermal are surging, with projections indicating annual funding could reach nearly $9 billion by 2030. This growth is driven by advancements in next-generation technologies, such as enhanced geothermal systems (EGS), which expand accessibility beyond traditional ...

Mercury NZ Ngā Tamariki Expansion: Fifth Geothermal Unit to Deliver 46 MW of Clean Power by 2026 By: Robert Buluma Mercury Ngā Tamariki Fifth Unit: +46 MW Geothermal Power NZ Mercury NZ is building a fifth geothermal unit at Ngā Tamariki Power Station near Taupō. Adding 46 MW net (total 132 MW), enough to power all Tauranga homes or Christchurch residential load. Mercury NZ Launches Ngā Tamariki Expansion – New Zealand’s Next Major Renewable Energy Project In May 2024, Mercury NZ turned the first sod on one of the most significant geothermal developments in the country this decade: the Ngā Tamariki Expansion Project. This ambitious project will see a fifth generating unit added to the existing four-unit Ngā Tamariki Power Station, located 20 kilometres northeast of Taupō in the heart of New Zealand’s geothermal wonderland. When completed in 2026, the new unit will deliver an additional 46 MW of net renewable capacity, lifting the station’s total output from 86 MW to an impressive 13...
